What Is Chelating Agent?
Chelating agents are any of numerous ingredients that bind with metal ions or metallic compounds, preventing them from adhering to a surface (such as skin, hair, or clothing) or causing contamination, such as in the case of trace amounts of iron. Examples are tetrasodium EDTA and tetrahydroxypropyl ethylenediamine. The EDTA complex is most common because of its broad effectiveness and compatibility with most cosmetic ingredients.
